What Do Angels Eat?

I walked into the living room and saw Princess Snifflefritz looking intently at an angel hanging on the Christmas tree.  She turned and looked up at me, "What do angels eat, mommy?"  I smiled and answered, "Angels don't need to eat, Sweety. They don't eat anything."  At that point, she paused, a little confused, unable to fathom the notion of never eating, said thoughtfully, " I think they eat sauce (ketchup). Yup, angels love sauce."

Coincidentally, I know of an Angel named Princess Snifflefritz who LOVES sauce (ketchup).
